Abstract (en)
[origin: EP2296259A2] The permanent magnet embedded rotating electrical machine includes a rotor and a plurality of flat permanent magnets. The rotor has on an outer periphery thereof a plurality of pairs of concave portions and a plurality of convex portions. Each of the convex portions is located between the pair of concave portions. The concave portions are formed at radially outward of respective adjacent magnetic pole ends of the permanent magnet. A bridge is provided in the rotor at an angular position about an axis of the rotor between opposed magnetic pole ends of two adjacent permanent magnets. Each concave portion at radially outward of the magnetic pole end of the permanent magnet is located close to the center of the same permanent magnet in relation to the bridge next to the permanent magnet in the circumferential direction of the rotor.
